A balloon and a section of a wall both have neutral charges, as shown below.
(The balloon and the wall are both positively and negatively charged)
A student rubs his hair on the balloon, giving it a negative charge. How will the charges be arranged in the wall when it is placed near the negatively changed balloon?

Responses
A. The charges in the wall will not change or rearrange at all.
B. The wall will have negative charges on the the side closer to the balloon
C. The wall will have its positive charges on the side closer to the balloon
D. The wall will now have all positive charges and no negative charges
B. The wall will have negative charges on the side closer to the balloon
why
When the negatively charged balloon is brought close to the neutral section of the wall, the negative charges in the wall will be repelled by the negative charges on the balloon. This will cause the positive charges in the wall to move closer to the balloon, resulting in an accumulation of negative charges on the side of the wall closest to the balloon.
are you sure
I apologize for the confusion. Let me correct my statement.
When the negatively charged balloon is brought close to the neutral section of the wall, the negative charges on the balloon will induce a separation of charges in the wall. The negative charges in the wall will be repelled by the negative charges on the balloon and will move to the side of the wall closest to the balloon, causing an accumulation of positive charges on the side of the wall closest to the balloon.
Therefore, the correct answer is actually:
C. The wall will have its positive charges on the side closer to the balloon
